brangelina buy private island

A few months back it was just a rumor ... now it has been confirmed that super-couple Brangelina have baught themselves a private island in Dubai's "The World" exclusive off shore development. "The World" is a cluster of 300 islands that collectively form a map of the world's continents and countries, which can be seen from outerspace!
Jolie and Pitt have chosen Ethiopia as their country of choice! Lucky Zahara!
What i didn't understand is not that they won't be living in it, but that they'll be using it to showcase a greener lifestyle and promote environmental issues to encourage people to lead more eco-friendly lives ... So, what are they going to do exactly?
We'll know soon enough!
They're neighbours will eventually include Sir Richard Branson and Rod Stewart.
